+Customizing the UI
+==================
+
+Customizing state colours
+-------------------------
+
+.. versionadded:: 1.10.11
+
+To change the colors for TaskInstance/DagRun State in the Airflow Webserver, perform the
+following steps:
+
+1.  Create ``airflow_local_settings.py`` file and put in on ``$PYTHONPATH`` or
+    to ``$AIRFLOW_HOME/config`` folder. (Airflow adds ``$AIRFLOW_HOME/config`` on ``PYTHONPATH`` when
+    Airflow is initialized)
+
+2.  Add the following contents to ``airflow_local_settings.py`` file. Change the colors to whatever you
+    would like.
+
+    .. code-block:: python
+
+      STATE_COLORS = {
+          "queued": "darkgray",
+          "running": "#01FF70",
+          "success": "#2ECC40",
+          "failed": "firebrick",
+          "up_for_retry": "yellow",
+          "up_for_reschedule": "turquoise",
+          "upstream_failed": "orange",
+          "skipped": "darkorchid",
+          "scheduled": "tan",
+          "deferred": "lightseagreen",
+      }
+
+
+
+3.  Restart Airflow Webserver.

+
+Customizing DAG UI Header and Airflow Page Titles
+-------------------------------------------------
+
+Airflow now allows you to customize the DAG home page header and page title. This will help
+distinguish between various installations of Airflow or simply amend the page text.
+
+Note: the custom title will be applied to both the page header and the page title.
+
+To make this change, simply:
+
+1.  Add the configuration option of ``instance_name`` under ``webserver`` inside ``airflow.cfg``:
